英文摘要The AMS-02 Collaboration has just published a high-precision measurement of the cosmic positron fraction e(+)/(e(-) + e(+)), which rises with energy from similar to 5 GeV to similar to 350 GeV. The result indicates the existence of primary electron/positron sources to account for the positron excess. In this work, we investigate the possibility that the nearby mature pulsars with ages of O(10(5)) yr are the primary positron sources. By fitting the data we find that the positrons from a single nearby pulsar, such as Geminga or Monogem, with the spectral index alpha similar to 2 can interpret the AMS-02 result. We also investigate the possibility that high-energy positrons are generated by multiple known pulsars in the ATNF catalogue. Such a scenario can also fit the AMS-02 data well. Future precise measurements of fine structures in the positron spectrum would be a support to the pulsar scenario.
